Description
Technical Field
The utility model belongs to the technical field of metallurgical industry production, a pipe connection spare in the metallurgical production is related to, specifically speaking is a novel install expansion joint fast.
Background
Expansion joints are also conventionally called compensators, or expansion joints. The expansion joint is a flexible structure provided on the vessel shell or pipe in order to compensate for additional stresses due to temperature differences and mechanical vibrations. The effective telescopic deformation of the working body corrugated pipe is utilized to absorb the dimensional change of pipelines, conduits, containers and the like caused by expansion and contraction due to heat and the like or compensate the axial, transverse and angular displacement of the pipelines, the conduits, the containers and the like. The compensator is arranged on the pipeline to compensate the thermal extension of the pipeline, thereby reducing the stress of the pipeline wall and the acting force acting on the valve member or the bracket structure.
The expansion joint of the corrugated pipe is made of metal corrugated pipe. It can be extended and retracted along the pipe axis and also allows a small amount of bending. Fig. 4 shows a conventional axial bellows expansion joint for axial length compensation in a pipe. The bellows expansion joint is composed of a bellows (an elastic element) forming a working main body of the bellows expansion joint, an end pipe, a guide rod, a flange and other accessories, the bellows expansion joint is connected with a pipeline through the flange, the flange needs to be welded on the pipeline on a construction site, and the construction process is complicated.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects, the utility model provides a novel install expansion joint fast has improved conventional bellows expansion joint structure, can realize the quick installation of job site, has improved work efficiency greatly, and structure itself is simple moreover, and is with low costs.
The utility model discloses a novel install expansion joint fast, including the bellows, take over, the guide bar, bellows both ends welding is taken over, takes over outside welding otic placode, has the through-hole on the otic placode, and the guide bar is in relative otic placode through-hole from top to bottom, and the guide bar has the screw thread to be fixed in on the otic placode through top and bottom nut outward, there is bead and the cooperation of pipe hoop draw-in groove in the takeover outside.
Furthermore, the guide rod is externally provided with threads, and two ends of the guide rod are fixed on the lug plate through nuts.
Furthermore, the pipe hoop consists of an upper connector and a lower connector, wherein the upper connector and the lower connector are connected through a bolt and locked by a nut; a groove is arranged in the middle of the inner wall of the clamp and used for placing a sealing ring; clamping grooves are formed in two sides of the inner wall of the hoop and are respectively matched with a convex edge on the outer side of the connecting pipe and a convex edge on the outer side of the pipeline.
Further, the sealing ring is made of rubber or elastic plastics.
The novel installation method for quickly installing the expansion joint comprises the steps that a pipeline joint and an expansion joint connecting pipe are respectively inserted into a sealing ring from two ends of a pipe hoop so that the sealing ring can achieve effective sealing deformation; and (3) placing the sealing ring in a groove on the inner wall of the pipe hoop formed by the upper connector and the lower connector of the pipe hoop, simultaneously enabling the convex edge of the pipeline and the convex edge of the expansion joint connecting pipe to be respectively buckled in corresponding clamping grooves in the pipe hoop, inserting the bolt and locking the bolt with the nut to finish the installation. The distance between the end surface of the pipeline and the end surface of the expansion joint connecting pipe is kept about 1.5 times of the line diameter of the sealing ring.
The utility model has the advantages that: the expansion joint structure of the conventional corrugated pipe is improved, quick installation in a construction site can be realized, the working efficiency is greatly improved, and the expansion joint structure is simple and low in cost.
